TRACK-SCRAPEB.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed October 14, 1916. Serial No. 125,680.

To all whom it may concern.

Be it known that I, An'rr-rnr. E. HUNT, a citizen of the United States, residing at Raymond, in the county of Pacific and State of \Vashington, have invented a new and useful 'lrack-Scraper, of which the following is a specification.

The present invention appertains to track scrapers, and aims to provide a novel and improved yet simple, inexpensive and efficient scraper applicable to the wheel of a saw mill carriage, or the like, for scraping the rail to clean the same.

It is the object of the invention to provide a scraper of the nature indicated com prising two duplicate sections of novel construction and interfitting one another in such a manner, as to enhance the utility and durability of the scraper.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made with in the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a side elevation of the scraper as applied to a wheel.

Fig. 2 is a section on the line 22 of Fig. 1. v

Fig. 3 is a section on the line 33 of Fig. 1.

Fig. 4 is an inside view of one section of the scraper.

Fig. 5 is a top plan view of said scraper section.

In carrying out the invention, the scraper is composed of a pair of longitudinal side sections or plates 1 set on edge and disposed in vertical planes. The sections are duplicates of one another and are in reversed positions. They are provided at their up per edges between their ends with curved recesses 2 to receive and accommodate the hub 3 of the wheel 4 of a saw mill carriage or other vehicle to which the scraper is applied. Those portions of the'sections 1 adjacent to the recesses 2 extend inwardly at an obtuse angle to provide lips 5 having their free edges overhanging the lower portion of the rim of the wheel l, to hold the scraper assembled with the wheel, and to assist in holding the scraper in proper operative position. i

The sections 1 are provided at their ends with interfitting portions, and for this purpose, each section 1 is provided at one end with a lug or block 6 extendingto one side toward the other end of the opposite section, said lug extending to the upper and lower edges and respective end of the section, and providing a thickened end for the section, which is provided with an inclined if-shaped ridge 7. The lugs 6 are adapted to ride upon the rail in front and rear of the wheel 4, to scrape foreign matter from the rail and deflect it to opposite sides oil of the rail. "The face of the lug 6 has a recess 8 terminating short of the end 7, and defining an inclined shoulder 9 adjacent to said end, and the recess 8 is adapted to receive the reverse end of the opposite section which overlaps the lug 6, and which is inclined, as at 10, to fit the shoulder 9. Each lug 6 has a secondary recess or cavity 11 tapered or decreasing in size from its mouth to its closed end and located within the outline of the recess or cut away portion 8, and the section 1 has an aperture 12 located centrally of the recess 11. The section 1 is provided adjacent to its inclined end 10 opposite the lug 6,-with a tapered secondary lug 13 projecting from its inner side, the same as the lug 6, toward the opposite section, and the lug 13 is of a size to fit snugly in the opposite recess 11. The section 1 has an aperture 14 extending through the lug 13 to register with the aperture 12 of the opposite section, and a pair of clamping bolts 15 extend through the registering apertures 12 and 14 at the opposite ends of the scraper, nuts 16 being threaded upon said bolts to clamp the scraper sections together. The outer sides of the scraper sections are countersunk or recessed,

as at 17 to receive the bolt heads and nuts.

The scraper will move along with the wheel 4:, as will be evident, and clear the rail when moving in either direction, and the lugs 6 are adapted to receive the wear in moving over the rail, and being solid, will withstand the wear and tear in a most eflicient manner. Shearing strain on the bolts 15 is eliminated by the interfitting portions of the scraper sections, so that the bolts only perform the oifice of holdin 1 a the sections together. The device can be readlly applied and removed when the sections are detached. The sections 1 can be readily molded, and being duplicates decrease the cost of manufacture.

Having thus described the invention, what is claimed as new is:

1. A track scraper comprising a pair of side sections, each provided at one end with a lug projecting toward the opposite section and adapted to slide upon a rail, the other ends of the sections overlapping and being secured to said lugs.

2. A track scraper comprising a pair of side sections, each provided atone end with a lug projecting toward the opposite section and adapted to slide upon a rail, said lugs having means for scraping the rail, the other ends of the sections overlapping the facesof said lugs, and means for clamping the last mentioned ends of the sections to the lugs.

3. A track scraper embodying a pair of side sections, each provided at one end with a lug projecting from its inner side toward the opposite section, said lug being adapted to slide on a rail and having means for scraping the rail, said lug having a recess, the other ends of the sections overlapping the faces of said lugs, the sections having secondary lugs projecting from their inner sides adjacent to the last mentioned ends and fitting in said recesses, and securing elements extending through the sections adjacent to their ends for clamping them together.

4. A track scraper embodying a pair of side sections, each provided adjacent to one end with a lug projecting from its inner side toward the opposite section, said lug being adapted to slide on a rail and having means for scraping the rail, the face of each lug having a recess receiving the reverse end of the opposite section, said recesses providing shoulders fitting the second mentioned ends of the sections, said lugs having secondary recesses within the outlines of the aforesaid recesses, the sections having secondary lugs projecting from their inner sides adjacent to their second mentioned ends and fitting in the secondary recesses, the sections having apertures extending through the secondary lugs and registering apertures centrally of the secondary recesses, and clamping elements extending through the registering apertures for clamping the sections together.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature in the presence of two witnesses.
